.TH std::ctype::~ctype 3 "2024.06.10" "http://cppreference.com" "C++ Standard Libary"
.SH NAME
std::ctype::~ctype \- std::ctype::~ctype

.SH Synopsis
   Defined in header <locale>
   protected: ~ctype();

   Destructs a std::ctype facet. This destructor is protected and virtual (due to base
   class destructor being virtual). An object of type std::ctype, like most facets, can
   only be destroyed when the last std::locale object that implements this facet goes
   out of scope or if a user-defined class is derived from std::ctype and implements a
   public destructor.

.SH Example


// Run this code

 #include <iostream>
 #include <locale>

 struct Destructible_ctype : public std::ctype<wchar_t>
 {
     Destructible_ctype(std::size_t refs = 0) : ctype(refs) {}
     // note: the implicit destructor is public
 };

 int main()
 {
     Destructible_ctype dc;
     // std::ctype<wchar_t> c; // compile error: protected destructor
 }
